For the last 2 weeks ZOB has changed around their Area 5 high altitude frequencies. They have replaced 121.075 with 128.450 in the Brecksville Sector (FL240-FL320), and moved 121.075 into the Franklin Sector (FL330 and above) replacing 119.725. Not sure if this is a permanent change ?

I'm trying to keep an updated database on ARTCC high altitude frequencies and sectors, if anyone notices any changes in their area, anywhere in North America, I'd always be interested in any updates posted here in the forum. Thanks.

The feeds that you can hear on this site may have a delay in them of about five seconds, so yes, they are basically real time. I just compared the feed I'm providing and there is about a four second delay. When I hear it on my scanner, it takes about four seconds to go through the Internet and reach you.

Thanks for the info. I'm always interested in any noted frequency changes for any of the enroute ARTCC's. Yeah the ZBW 118.425/126.225 thing has been going on for a few years now, same with ZNY 134.375/125.325 I've also heard 121.125 used in that sector. That ZBW 118.550 is a new one for me, never heard it in use before ?

Just heard United 71 on 118.55 "leaving FL390 for FL280". UAL71 is going to EWR...

I pulled up some Moncton Center archives around the same time and heard NAT traffic getting handed off to 118.55 as well, the routes on these flights would seem to confirm it replacing 134.95 (Augusta High Sector 02). Thanks again for the report !

Here ya go Jetscan, maybe a new one for you...at this moment ZNY 134.375 is being used in place of ZNY 128.3. This frequency typically backs up 125.325 - it was doing that earlier today - but I've never heard it backing up 128.3 before.

Thanks. I also heard ZBW using 135.075 in place of 125.575 this afternoon, but just briefly like it was for a test. I also see 118.550 is still in use for 134.950, and a few days ago heard 132.900 being used as well.

you interested in the merging of sectors? Like when two sectors operate on one frequency later at night?

Yes. I've got a pretty good handle on sector configurations during the day (that chart I attached in the other thread), I haven't got around to doing the same for overnight configurations yet, so I'll take whatever you have.

For ZBW, 135.8 (low) and 124.525 (high) combine into a high/low sector at night that operates on 135.8

Also for ZBW, 134.3, 134.0 and 125.575 merge into one high/low sector at night that operates on 134.3 (99% sure about this one...) I can hear the ground controller on 125.575 (barely) at night but couldn't hear any planes. Eventually I found that they were on 134.3 so I know this part for sure. I'm 99% sure that 134.0 is also part of this merger.

ZNY 132.2 becomes a high/low sector at night, I'm just not quite sure yet what sectors are merged together. Still working on figuring that out.

There is a ZNY 132.20 feed here on LiveATC with both good controller and aircraft reception, from listening to the archives during the overnight hours (between 05Z and 11Z), the controller was working high sectors 8/9/10 and low sectors 25/26/27 with all aircraft on 132.20.

8 = 124.779 = 134.3210 = 133.4725 = 135.4526 = 133.1727 = 132.20

The above sector numbers are based on ZNY NOTAM 08-01 "Radio Communications Frequencies" from July 15, 2008, the latest one I could find.

On the subject of ZNY, can anyone confirm if Sector 8, 124.77, is ever used ? It's listed as the BRNAN sector, FL330 and above, overtop sectors 9 and 10. I have not heard it in use for a few years now ?

From that NOTAM sector 26 is listed as 120.02 but from what I've heard they seem to use 133.17, is 120.02 still used, maybe as a backup ?

I noticed today that ZBW 124.525 will use 132.3 as a backup if needed. Today there was some interference on 124.525 (you could hear it on my feed) and ATC had everyone go over to 132.3. Within a half hour they were back on 124.525.

Also, ZNY 121.125 is active. I can hear the ground controller for 133.5 on this freq. All the aircraft are still on 133.5 but for some reason ZNY is transmitting on both 133.5 and 121.125. Would be nice if it stays like that
